以基督精神重新解读米开朗基罗《创世纪》中上帝形象

五百年来中外学界一直用人文主义观点，把米开朗基罗在《创世纪》中的上帝形象解读成人间英雄，将其画旨归结为歌颂人的创造和伟大。其实，米氏《创世纪》中的上帝形象是对摩西的“烈火”、以赛亚的“长衫君王”和但以理的“银发圣父”等上帝原型的承续和再创，其画旨是表达人的悲郁无助和对神的伟大救恩的颂赞和呼求。     

网络环境对财务风险预警系统的影响

近年来，随着网络在财务管理工作中的应用，财务风险发生了显著的变化。建立网络环境下的财务风险预警系统已经迫在眉睫。我国对这一领域的研究无论在理论上还是在实践上都较薄弱，财务预警管理也是我国企业迫切需要解决的问题。     

强化学习型匝道控制模型的研究

高速公路上的交通堵塞造成了道路利用效率低下，并伴随着能源消耗和环境污染问题，因此各种各样的高速公路控制方法应用于缓解交通堵塞。本文提出强化学习型匝道控制模型，该模型以交通流模拟为预测工具，以人工智能的强化学习为最优化选择模型，并具有一定的自主性、有记忆功能和性能反馈功能，且是一种动态的过程。应用JAVA针对不同的交通状态进行模拟再现，模拟结果表明匝道控制模型对于减少交通堵塞具有显著的效果。     

Adaptive agent-based manufacturing control and its application to flow shop routing control

The manufacturing industry is currently facing unprecedented challenges from changes and disturbances. The sources of these changes and disturbances are of different scope and magnitude. They can be of a commercial nature, or linked to fast product development and design, or purely operational (e.g. rush order, machine breakdown, material shortage etc.). In order to meet these requirements it is increasingly important that a production operation be flexible and is able to adapt to new and more suitable ways of operating. This paper focuses on a new strategy for enabling manufacturing control systems to adapt to changing conditions both in terms of product variation and production system upgrades. The approach proposed is based on two key concepts: (1) An autonomous and distributed approach to manufacturing control based on multi-agent methods in which so called operational agents represent the key physical and logical elements in the production environment to be controlled – for example, products and machines and the control strategies that drive them and (2) An adaptation mechanism based around the evolutionary concept of replicator dynamics which updates the behaviour of newly formed operational agents based on historical performance records in order to be better suited to the production environment. An application of this approach for route selection of similar products in manufacturing flow shops is developed and is illustrated in this paper using an example based on the control of an automobile paint shop.     

有限宽裂纹板受一对集中剪力时弹塑性解

针对运用断裂力学传统方法进行裂纹尖端的弹塑性应力场分析均为小范围塑性区的假定，不能准确反映塑性区应力情况的问题，利用裂纹线场分析方法，对理想弹塑性材料的有限宽平面板在裂纹面受到一对集中剪力作用时裂纹线附近的应力场及弹塑性边界进行了分析。不采用小范围塑性区的假设，直接通过将裂纹线附近弹塑性边界上弹性应力场与塑性应力场的匹配，获得了裂纹线附近弹塑性应力场的解析解以及弹塑性边界上单位法向量的表达式。用裂纹线分析方法可以准确地反映裂纹附近的弹塑性应力分布，该种方法的应用将成为断裂力学的一个重要发展方向，对石油天然气构造应力分析、材料力学分析具有参考价值。     

Improving traceability in continuous processes using flow simulations

Traceability is normally difficult to achieve in continuous processes, since there are no natural batch structures. In this article, we demonstrate flow-based simulation using process data to improve traceability in a continuous pelletising process. Using the simulation model, the engineers could test the impacts of process disturbances, identify cause and effect relations and aid control in case of process disturbances. In a field trial where the chemistry of an additive was varied during production of a special product, the simulation forecasts predicted the level of the chemical content after the plant within the errors that the engineers found acceptable.

知识流模型及其在航天企业中的应用

知识管理的理论和实践吸引了众多学者和企业家的关注,但在具体的实施方法上一直没有形成共识。管理的对象是“知识”,对于知识流动的理解、监测乃至控制是顺利实施知识管理项目的基础。已有的研究对知识流的讨论集中于描述概念,或通过统计分析或调查问卷得到对专利、引用等知识流动的描述。把Petri网理论用在对知识流进行刻画中,提出知识流的Petri网模型,能够描述知识分布的拓扑结构、知识存量、一定时期的知识流量和流速,使得管理人员便于监控和管理知识流动,更好地实施知识管理。把基于Petri网的知识流模型应用于航天企业中,通过实证分析说明该知识流模型对知识流动的刻画能力,并通过对现状的分析,为改进知识流动效率,实现知识管理目标提供支持。
